Dr. Mark Hoddle, a research scientist at the University of California at Riverside, is establishing the biological control agent, Tamarixia radiata, a parasitoid that attacks Asian citrus psyllid (ACP) nymphs, an invasive pest infesting citrus and spreading the deadly huanglongbing disease.

We have developed short, descriptions of research projects that aim to help in the fight against HLB. These projects include traditional breeding and genetic engineering to create resistant citrus varieties, psyllid modification, using other organisms to deliver HLB-resistance genes, and early detection of the bacterium in trees.
